fix(VMenu): Use correct aria handling for menus.

[viktorkratz]

Because of the use of aria-own, vmenu's could not be used with screen readers.

Description

Vemnu uses aria-control and no longer aria-owns because with aria-owns it was not possible to use the menu with some screen readers. It could be improved by setting role="menu" on the slot and role="menuItem" at every single item, but this could break things depending on slot content.
